Gardening fluid connection device

ABSTRACT

A gardening fluid connection device contains a body including multiple retainers, a resilient element, and a fitting sleeve including multiple spaced engagement teeth. The resilient element abuts against the body and the fitting sleeve. The body includes a stop rib, and the multiple spaced engagement teeth are pushed by the resilient element to abut against the stop rib. The body includes at least one retaining element, each retaining element is located on a first side of each spaced engagement tooth, and a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, hence the fitting sleeve is rotated reciprocatingly to open or close of the gardening fluid coupling device by using the stop rib, each retaining element, each spaced engagement tooth and the resilient element, and each retaining element is stopped when moving to a second side of each spaced engagement tooth.

TECHNICAL FIELD

The present disclosure relates to a gardening fluid connection devicewhich is employed to connect with a water spray gun, a sprinkler or awater hose.

BACKGROUND

A conventional gardening fluid connection device, such as disclosed inTW Patent Nos. 260238, 532442, 11319072 and U.S. Pat. No. 7,021,669, isemployed to connect with a water supply device (e.g., a water spray gun,a sprinkler, or a water hose). The conventional gardening fluidconnection device contains a fitting sleeve reciprocatingly rotatedleftward or rightward so as to open or close the conventional gardeningfluid connection device. When the fitting sleeve is stopped after beingrotated, the user knows the conventional gardening fluid connectiondevice is located on an opening position or a closing position.Alternatively, the user knows the conventional gardening fluidconnection device is located on the opening position or the closingposition after pressing the fitting sleeve. Furthermore, a conventionalgardening fluid connection device such as disclosed in U.S. Pat. No.7,021,669 contains an L-shaped depression defined in the fitting sleeveso that the stop rib of the fitting sleeve slides in a stopping face ofthe depression when being rotated to the closing position or the openingposition, hence the conventional gardening fluid connection device isnot positioned.

DETAILED DESCRIPTION

With reference to FIGS. 1 to 3, a gardening fluid connection deviceaccording to a preferred embodiment of the present invention comprises:a body 10 on which multiple retainers 101 are retained, a screwingsleeve 20 mounted on a first end of the body 10 and configured toconnect with a water hose, a resilient element 30, and a fitting sleeve40, which are fitted with a second end of the body 10 The resilientelement 30 and the fitting sleeve 40 abut against each other so that thefitting sleeve 40 rotates along the body 10 reciprocatingly and pushesthe resilient element 30 so as to open or close of the gardening fluidcoupling device, hence the multiple retainers 101 of the body 10 areremoved or retained when the fitting sleeve 40 presses the resilientelement 30 or is pushed by the resilient element 30 so that the multipleretainers 101 of the body 10 connect with or remove from a water supplydevice, such as a water spray gun or a sprinkler. The body 10 includesmultiple flexible teeth 11 arranged on the first end thereof, a threadedsection 12 formed inside the multiple flexible teeth 11 and configuredto screw with the screwing sleeve 20, a stop rib 13 arranged on thesecond end of the body 10, one or more than one locking element 14(i.e., each locking element 14 is a boss) formed inside the stop rib 13,multiple limitation elements 15 arranged inside the one or more than onelocking element 14 and away from the stop rib 13, and multiple spacedorifices 16 configured to accommodate the multiple retainers 101respectively and located adjacent to the stop rib 13. In thisembodiment, each of the multiple limitation elements 15 is definedbetween any two of the multiple spaced orifices 16 and is an extendingrib.

Referring further to FIGS. 1 to 3, the body 10 includes one or more thanone retaining element 17 (which is a protrusion). Each retaining element17 is defined between each limitation element 15 and each spaced orifice16. The body 10 further includes a surround seat 18 arranged on a middlesection thereof and abutting against the resilient element 30. In anembodiment, the resilient element 30 is a spring. The fitting sleeve 40(as shown in FIG. 4) includes a fixing seat 41 formed on a middlesection of an inner wall of the fitting sleeve 40 and abutting againstthe resilient element 30. Multiple guide zones 42 are defined byelongated ribs and correspond to the multiple spaced orifices 16respectively, wherein the multiple guide zones 42 abut against themultiple retainers 101 individually. Multiple spaced engagement teeth 43are defined between any two adjacent of the multiple guide zones 42 soas to be pushed by the resilient element 30 and contacts with the stoprib 13 of the body 10. And the one or more than one locking element 14is located beside each of the multiple spaced engagement teeth 43 sothat the resilient element 30 pushes the fixing seat 41 of the fittingsleeve 40 and the surround seat 18 of the body 10.

The fitting sleeve 40 further includes one or more than one elongatedshoulder 44 respectively corresponding to and located above the one ormore than one retaining element 17 so that the one or more than oneelongated shoulder 44 moves across the one or more than one retainingelement 17 when the fitting sleeve 40 is rotated. Each elongatedshoulder 44 has a stopping face 45 defined on one side thereon so as toform a defining space 46, such that each limitation element 15 islocated in the defining space 46 and is limited by each elongatedshoulder 44 and the stopping face 45 when the fitting sleeve 40 rotatesreciprocatingly. A width of each of the multiple spaced engagement teeth43 is equal to a rotation distance of the fitting sleeve 40 in anembodiment.

Referring to FIG. 5, when the fitting sleeve 40 is located on a closingposition, each elongated shoulder 44 is located above each retainingelement 17 of the body 10 so that the fitting sleeve 40 does not presseach retaining element 17 while the fitting sleeve 40 is pushed by theresilient element 30 so that each spaced engagement tooth 43 is biasedagainst the stop rib 13 of the body 10, and each locking element 14 islocated on a first side of each spaced engagement tooth 43 (asillustrated in FIG. 6). In this arrangement, each limitation element 15of the body 10 contacts with the stopping face 45 of the fitting sleeve40 and each of the multiple retainers 101 is pushed by each of themultiple guide zones 42 so as to connect with a coupling opening of thewater supply device. When the fitting sleeve 40 is rotated to an openingposition (as shown in FIGS. 7 and 8), each elongated shoulder 44 movesaway from each retaining element 17 so that the fitting sleeve 40presses the resilient element 30, and each locking element 14 and eachspaced engagement tooth 43 are pushed by the fitting sleeve 40 to pressthe resilient element 30 so that each spaced engagement tooth 43 removesfrom the stop rib 13 and moves along each locking element 14. When eachlocking element 14 moves to a second side of each spaced engagementtooth 43 (as illustrated in FIG. 9), each spaced engagement tooth 43 isnot forced by each locking element 14 and is pushed by the resilientelement 30 so as to urge the stop rib 13 and each locking element 14 torotate toward the second side of each spaced engagement tooth 43.Preferably, each limitation element 15 contacts with each elongatedshoulder 44 so as to maintain the fitting sleeve 40 on the openingposition, and the fitting sleeve 40 (as shown in FIG. 10) and theresilient element 30 are pressed until each retainer 101 of the body 10removes from each guide zone 42, thus removing or fixing each retainer101 from or into the coupling opening of the water spray gun or thesprinkle. Thereby, the gardening fluid coupling device is opened orclosed easily by way of the stop rib 13 and each locking element 14 ofthe body 10, each spaced engagement tooth 43 of the fitting sleeve 40,and the resilient element 30.
